为获得某新型舰用燃气轮机进气系统综合模拟实验台的气动阻力特性，本文利用实验与数值相结合的方法研究了其气动特性及流场特性。首先在实验台上完成不同工况下的模拟实验，进行气动参数的采集，并计算对应工况下的内部流场，分析各截面上总压损失分布及流阻特性。结果表明，在不同工况下该进气系统内部流场主流区流动平稳均匀，各部分总压损失较小且分配合理，且设计工况阻力系数最小。该新型舰用燃气轮机进气系统综合模拟实验台具有良好的气动特性。%For the sake of aerodynamic resistance characteristic of a new simulation experiment rig for marine gas tur-bine intake system, in this paper, the aerodynamic characteristics and flow field characteristics were studied by the combina-tion of experimental study and numerical simulation. Aerodynamic parameters were collected when the simulated experi-ment at the different conditions were done by the experimental system, the numerical simulation of the flow field at the same condition was made and the total pressure loss distribution and aerodynamic resistance characteristic for the different cross sections were analyzed. The results show the main flow of intake system internal flow field at the different conditions keep flow stable and uniform, total pressure loss of different parts allocation is reasonable, the resistance coefficient of the design condition is lowest, the simulation experiment rig has good aerodynamic characteristics.
